I've heard a high pitched ringing sound in my ears my ENTIRE life?

Ok so I'm almost 11. Please don't report I need answers! I'm suffering at night day and lunch!
For my entire life I have heard this high pitched ringing sound in my ears (both) and it has never stopped, 24/7.It is so annoying and get very loud when I come close to technology. I saw 10s of doctors when I was little but they all said I was just in fairy land.
I have told my parents and they'll try hard to stop it cuz I do complain its that loud, by giving me a heat pack or dimeatape ear drops, anything but it just won't stop. My has told me I was supposed to have grommets when I was little but we passed cuz I used to have sensitive ears. I really need answers and mum has thought about taking me back to a doctor now I'm older. I have found an app on the iPad, iPhone, iPod called teen-a-noise which almost makes that same high pitched sound. We r planning on taking the iPad and playing the sound for the nose ear throat specialist but if there's anything I can do else wise to stop it please tell me, I hope a. Doctor sees this! I have research and read that other people have suffered this. Tuttinus is a BIG one out there but I've had it for my WHOLE life it's not just on and off again. Please help me I really want to stop it! Answer Please I'm DESPERATE TO MAKE IT STOP

Don't worry honey. I have the same issue when I wake up sometimes it comes, sometimes it goes. There isn't a cure for it, but there's a way to prevent it from coming back. Since you're so young, you may need to talk to your parents and ask them to put you on a diet that doesn't require you eat a lot of sweets, caffeine, and salts. Don't listen to loud music, or play the tv loud while sleeping, no ipod for awhile and don't use headphones too loud. Take vitamin supplements everyday and stay active. It could be from anything, bacteria, allergies, tumors, ear infections anything.
